Garcia was riding his bicycle westbound in a crosswalk when a light-colored, 4-door sedan struck him at 2:49 a.m. Police said Garcia went against a red light and the car was going 70 mph when he was hit.

Garcia was thrown 150 feet through the intersection. While Garcia lay dying from head trauma, the driver fled on Natividad Road, police said.

"There's no doubt that person would know based upon how bicyclist was hit, and how significantly bicyclist hurled through intersection, that there had to be a significant collision," police Cmdr. Vince Maiorana said.

As of Monday night, Salinas police had not yet identified or found the driver, and investigators are asking people who heard or saw anything to come forward with information.

Investigators say both the victim and the driver contributed to this collision. The cyclist went against a red light, and the driver was driving at about 70 miles per hour on a residential road.

Garcia's friends created a memorial with flowers and a ghost bicycle on a patch of sidewalk near where he died. A memorial group ride has been organized for Friday at 1 p.m., starting at Salinas High School on South Main Street.

"This group ride is for our fallen rider Adrian and to show to motorists that cyclists have every right to be on the roads as a car," organizers wrote on Facebook.

Saturday's deadly hit-and-run was the sixth fatal traffic collision in Salinas this year and the first involving a bicyclist, police said.

Anyone with information about the crash is encouraged to call Salinas police at 831-758-7980.
